Abstract

The invention discloses a voltage test device and a voltage test method. The voltage test device is used to test a first circuit board, wherein the circuit board comprises a fist connector. The voltage test device is couple with a power supply unit so as to obtain input voltage from the power supply unit, and the power supply unit provides a power supply for the first circuit board. The voltage test device comprises a voltage generating unit, a connection part and a comparison module, wherein the voltage generating unit is used to receive the input voltage and converts the input voltage to a preset voltage; the connection part is used to be coupled with the fist connector of the first circuit board and obtain a first measurement voltage from the fist connector; and the comparison module is coupled with the connection part and the voltage generating unit separately, receives the first measurement voltage and the preset voltage and compares the first measurement voltage with the preset voltage to provide the test result.

Description

technical field [0001] The present invention relates to a test device, and in particular to a voltage test device and a voltage test method. Background technique [0002] With the rapid progress of the electronics industry, the quality and variety of related products circulating on the market are changing with each passing day. The rapid popularization of computers is an obvious example. The motherboard is an indispensable and important component of the computer, and its quality can determine the performance of the entire computer. Therefore, in order to improve the quality of the computer, manufacturers usually improve the reliability of the motherboard through testing. [0003] In the process of production, in order to perform a functional test on the motherboard, the traditional method is to install the necessary electronic components on the motherboard and directly power on for testing. For example: the central processing unit (CPU) on the motherboard is powered only a...
